Definition: How can DNA methylation patterns be used to predict biological age?

Biological age refers to the functional age of an organism, which may differ from its chronological age. It is influenced by various factors, including genetics, lifestyle, and environmental exposures.

Recent research has shown that DNA methylation patterns can be used as biomarkers to predict biological age. By analyzing the methylation status of specific regions in the genome, scientists can develop epigenetic clocks that estimate an individual’s biological age.

Epigenetic clocks are mathematical models that use DNA methylation data to calculate an individual’s biological age. These clocks are trained using large datasets that include both chronological age and DNA methylation profiles. By comparing an individual’s methylation patterns to the established epigenetic clock, their biological age can be estimated.

The accuracy of DNA methylation-based age prediction has been demonstrated in various studies. These epigenetic clocks have been shown to correlate with age-related diseases, such as cardiovascular disease, cancer, and neurodegenerative disorders.

Furthermore, DNA methylation-based age prediction has potential applications in personalized medicine, as it can provide insights into an individual’s overall health and susceptibility to age-related diseases. It can also be used to assess the effectiveness of interventions aimed at slowing down the aging process.
